    kernel/rmdir: Return EBUSY if the dir is a mount point for a mounted fs.
    
    See: http://pubs.opengroup.org/onlinepubs/009695399/functions/rmdir.html
    
    It was already documented like that in the manual page.
    
    While here, also document that we return EINVAL if the last component of
    the path is "." or ".." (taken from FreeBSD).
